To a/ZZ whom t may concern:

` ing drawings, which illustrate an example of apparatus in accordance therewith.

In the said drawings, Figure l shows in transverse sectional elevation corresponding to the line A B of Fig. 3 a conveyer comprising four stages, wh'ich are respectively indicated by the reference-numerals I II III IV and are mounted on rollersin a tunnel. Fig. 2 is a transverse sectional elevation corresponding to the line C D of Fig. 3 and to the mainshaft to which the motion is imparted by a dynamo-electric mot'or. Fig. 3 is a longitudinal sectional elevation ot' a transmission-station, Fig. 4 is a plan of a portion of the conveyer and of a little more than half of a transmission-station. Fig. 5 is a plan of a portion of the main stage IV, wherein the Hoor-plating has been removed in order the better to show the arrangement and joining Fig. 6 is a cross-sectional elevationscorresponding to Fig. 5. Fig. 7 is a plan of a portion of one of the smaller stages I II III, resembling in its general features the planof the main strip` IV shown in Figj. Fig. 8 is a cross-section corresponding to Fig. 7.

Each stage, whether of greater or of less width, is mounted on a flexible longitudinal metal beam 1, formed, as shown in Figs. 5 and 6, by joining together iron sections having their ends at forty-tive degreesl to their axes and secured together bymeans of fish-plates,

so that the beam can beibent both in a vertical and in a horizontal plane. Small flooring boards or panels 2, of wood or of thin sheet metal, are secured fcentrally to the upper anges of the beams 1. The edges of these panels bear on the outer beams 3 3', of corrugated sheet-iron, upon the surfaces ofwhich they canlightly slide when the stages pass over curved-portions. Light supports or arms 4, secured at regular intervals to the beam 1 apart.

beneath the panels 2, sustain certain ot' the panels 2 and by forming cross-tie bracing serve to maintain the form of and distance between the beams, while in no Way impairing the flexibility of the stage in a horizontal direction.

The longitudinal beam l of each stage bears successively by means of its lower tlanges upon the flat bottom of a groove in a roller 5, which is or may be a driving-roller Wit-h a .pulley and against the flat bottom of a groove in a similar roller 5', which is merely a supporting-roller. These rollers are separated by a distance ofaboutfive meters. Supporting-rollers 6, similar to the rollers 5', are arranged under the outer beams of each stage and also at a distance of about Iive meters Posts 7, serving as supports, are arranged and secu red at regular intervals upon and along the edge of each stage. The supports of each stage can be connected by or have substituted for them hanging straps.

Along the back edge of the stage IV is al movable back 8,formed of open-workarrd having the same mobility and iexibility as the stage of which it formsa part, and along and against this back are arranged at intervals seats 9, which may either be xed or made to turn down. The backS may be covered to a suitable height by a metallictrellis. A contact-conductor may be located at 10so that besides the stationary lamps Il in the tunnel there may be lamps 12, which travel with the large strip IV.

At intervals of about fifteen meters there is located upon a frame 13, carried by a masonry support 14, a dynamo-electric motor 15 Whose rotary movement is reduced and transmitted to a shaft 16, as by a smalll pinion 17, Fig. 3, engaging with a large wheel 18, keyed on the shaft 16. A worm and worm-wheel might be substituted. This transmitting and reducing gear may be immersed in an oil-bath. The shaft 16 extends to a standard '19, which supports its end, and upon this shaft there are keyed electromagnetic friction-'clutches 20 2l 22 23, which when energized are adapted to engage pulleys 20 21 22 23', and thus to drive the stages either directly or through belts or cables. Each of the pulleys 20 2l' Each ot these belts, which are IOC respectively numbered 24 24', 25 25', 26 26', and 27 27', actuates a pulley formed in one piece with one of the rollers 5, by which the longitudinal beam ot' a stage is moved and supported.

The'rollers 5 belonging to the large stage IV are carried by supports 28 28', Fig. 3. Means are provided for enabling the tension of the belts or cables to be regulated as desired. The rollers 5, by which the small stages I II III are moved, and the rollers'G, by which they are supported, are carried by supports 29,10- cated at one side of the supports 28 28', and each of these rollers may be furnished with a device, as one or more regulating-screws, on yielding supports, whereby its height may be regulated. The supporting-rollers 6 .of the outside beam on the right-hand side of the stage IV are provided with suitable supports 30, which may be simply brackets arranged against the wall of the tunnel. The other supports are arranged in such a way that it is easy to walk around them. They may be constructed of masonry or armored cement, and their upper part may be of asphalt.

The series of supporting-rollers 5', whose axes are located in the vertical plane containing the axis of the shaft 16, is carried by two transverse girders 3l, which may, if necessary, be raised so as not to extend below the rollers and be stayed to other girders, so as to form a strong support of the least possible height.

The tunnel within which the conveyer is arranged is generally of approximately rectangular cross-section with a liat or slightlyarched roof. When inthe lower part of this tunnel there occurs a transverse obstruction-as, for example, a sewer or another tunnel or channel-over which it is necessary to pass, the series of supports may be inter-- rupted and the beams supported by simple carrying-wheels of sutiicient number and diameter.

An explanation has already been given of the construction of the stages, which, while differing in breadth and speed, are all, ot'similar construction, Figs. 5, 6, 7, and 8 enable the constructional det-ails to be readily understood.

The sections ot' I-iron ot' the flexible beam 1 are beveled at the ends to enable them to run on the bottom ofthe groove of each roller 5 or 5 with the least possible amount of noise. Thesesectionsareconnected together by iish-plates 32, whose bolts pass through them from one side without play and from vthe other side with a little play, caused by making the holes slightly oval. By this arrangement the flexibility of the beam in a vertical plane is increased. The movement of the beam in the horizontal plane is prevented by flanges cast on the rollers.

VOn curves the thrust resulting from the curvature of the beam is taken by a row of balls, against which the boss of the roller bears, thereby reducing the lateral friction.

On each side of the beam l and against it at intervals of about a meter there are secured by one end each the arms 4 already mentioned. The other ends of these arms are fixed to the corrugated wall of the outer beams 3 3 to the right and left and to the wooden bars 33, above which the corrugations of these beams are supported.

To the upper part ot each beam 3 3' there are iixed angle-irons 34E, which carry the ends ot' the boards 2, which are bolted to them with play, the bolt-hole being slightly oval to enable the ends of these boards to slide to a slight extent on the top of each lateral corrugated beam while passing around a curve.

Each bar 33 has a length of one meter and is fixed at its middle point 35 to the end ot the arm 4, and at each end 36 it is cut at an angle. When the stage ot' the conveyer becomes curved the part 33 remains straight and normal to the arm 4, its ends moving slightly in relation to the corrugated wall. When the latter is developed on a curve and becomes curved itself, the bars 33 have the appearance of a number of linesforming a polygon approximately tangential to the curve. The oval form of the holesV in the ends of each bar 33 enables the said ends to be slightly displaced.

Each motor, which is located at fifteen meters from those adjacent to it, drives Iifteen meters of the conveyer; but, as has been seen, the stages ofthe conveyer are independent of one another, so that one stage can be `stopped without stopping the others. When it is desired to stop one stage, it is necessary so to modify and regulate the speed of the stages that remain in motion as to enable a passenger to step from one stage to another without inconvenience. The independence of the stages enables them to be successively started and to be driven at different speeds.

Each motor is provided with a separate switchboard; but all the motors maybe placed in circuit at one operation from a central station, and all the electromagnetic clutches of the same stage are arranged in series on the main wire, so that they may be simultaneously energized. Y

The motors, which, as already stated, are located at fifteen meters apart, develop a maxinum motive power of about three horsepower. The armature is wound with thick wire, so that at starting each motor may develop fou r horse-power without sensibly heating its armature.

To eiect the starting of the conveyer, after all the motors have been placed into circuit all the electromagnetic clutches of the stage I are energized. When this stage has attained its maximum speed, (about four kilometers per hour,) the clutches of the stage II are energized. When this stage has attained its maximum speed, (about veight kilometers per hour,) the clutches of the stage III are energized. Finally, when the speed of this stage has attained its maximum (about twelve IZO `to engage; a driving-pulley and roller kilometers) all the clutches of the large stage IV are energized, the starting of this stage being facilitatedpby the movement of the adjacent stages. The Astarting or the restarting of the conveyer may, moreover, be commenced withany stage. It is obvious that the number and thewwidth of the stages constituting a eonveyer` may be varied.
